We don't know the performance impact of running DLSS on the Switch 2. Running a game at 1080p, upscaled to 4k with DLSS on the Switch 2 might perform worse than just running native 1440p. Tensor Cores are used for DLSS and the Switch 2 has 64, the same as the RTX 3050 Laptop, the lowest end ampere gpu for pcs. So Upscaling with DLSS may be quite situational for whether it's worth using or not. I doubt many are trying to upscale to 4k with a 3050 laptop. We're going to see DLSS more for upscaling to 1080p/1440p than 4k, which will need a lot less performance out of those tensor cores, and probably will be used a lot more by third party than by Nintendo. It seems even for Switch 1 titles like BOTW Nintendo has opted to use native 1440p rather than use any DLSS. |
It's difficult to find specific benchmarks for the RTX 30350 laptop that show 4K DLSS performance vs 1440p native I guess it's not the sexiest GPU so didn't attract a lot of coverage), though generally the consensus seems to be that using DLSS is highly recommended for the GPU precisely because of it's underwhelming specs... Here's Cyberpunk benchmarks using DLSS on a RTX 3050 (desktop version, obvs a bit more powerful). It shows a significant increase in frame rates when using DLSS no matter the resolution. I'm admittedly no expert but in what scenario would it not be beneficial to use DLSS? In it's recent iterations there's negligible visual degradation/artifacting unless the gulf in native vs output res is big. For MKW, even forgetting 4K DLSS Performance, why would it not be better to run the game at 1440p DLSS balanced (1080p internal) than native 1440p, then free up headroom for upping environmental density or whatever? Genuine question. If I remember correctly TOTK used FSR on S1... If S1 can handle upscaling surely S2 should find it a breeze. Can you show an example where any GPU has worse performance when using DLSS vs native? (again, genuine question, trying to figure all of this stuff out) Could it be Nintendo just being Nintendo & inexplicably ignoring the feature, just like AA? |
The video you posted shows slightly worse performance with 4K DLSS-Balanced than 1440p native. Though dropping DLSS to performance mode would likely make it run just as well.
But that video is an RTX 3050 8GB desktop card which has 80 tensor cores compared to the 64 in the 3050 mobile, and the 64 believed to be in the Switch 2. So it will be faster at upscaling with DLSS.
My point was only that 4k using DLSS may run worse than native 1440p, not that using DLSS in some form wouldn't result in better performance for an equivalent or better image quality.
Using DLSS for 1440p instead of running native 1440p would leave them more GPU power on the table for other areas but if they have the power for what they want to accomplish there's no need.
Though a lot of Nintendo games would benefit from using DLSS as the upscaling process performs anti-aliasing which is something a lot of Nintendo titles don't even attempt to do, as you mentioned, and it's been shown that using DLSS to upscale to a resolution can result in better image quality than just running that resolution natively.
So I think there probably is a place for DLSS in Mario Kart that would make sense and be an improvement but at the end of the day 1440p60 is very respectable.
Whether they tested DLSS and decided not to use it, or didn't even consider using it, only Nintendo knows.
